Clones and stores remotes and fobs · 6
I've been happy with my Zero, cloned some friends apartment building door fobs, and using it for missing remotes for TV's and fans.
May 2026 · commentI use it to clone remotes of "dumb" devices and emulate them with ESPHome to make them "smart" fully offline under my control.
Jul 2026 · commentIt’s been very useful to me in so many ways, from fob management, to one IR, to rf scanner and other stuff

that build quality and the availability of firmwares to do what you are looking for with just a quick flash makes them handy AF

Flipper Zero was great because it enabled access to protocols that are usually quite hard to mess with.

What people warn about
Limited practical use beyond novelty · 3
Some people get a lot of use out of it, but if you just saw that list of hardware and couldn't think of one area you'd apply it in, it's probably not going to be a useful device for you.
Jul 2026 · commentI still don't think I've seen an actually useful application for a Flipper Zero.
Apr 2026 · commentmost people who bought a Flipper Zero didn't really have a use for that either
May 2026 · commentHacker hype in marketing · 3
I'm sorry, but I'm so sick of seeing "omg hacker man" mystique surrounding flipper, which is exactly what they want because it drives sales.

Apr 2026 · commentI guess all the clickb8 tiktok bs which casts the flipper as some sort of super hacking device worked.

They may have created good hardware, but their software and discord community just sucked.
Jul 2026 · commentIt begs the question why have an official firmware if it's not at least slightly maintained.

What hackers pick instead
- ESP32 Bit PiratePeople recommend it as a cheap ESP32 tool for hardware protocols, with browser control. Critics say it needs protocol handlers written by hand and suspect AI-generated code.13recommend
- Kode DotPeople recommend it as an all-in-one pocket device that needs no extra shields or cables, with built-in NFC. Critics agree the roughly $200 base price is too high.7recommend
- Bus Pirate by Dangerous PrototypesA handy hardware device, still the most popular model and actively developed and supported. Some critics find its bytecode-style syntax complex.6recommend

Its value is to provide a standardized hardware platform for (white hat) hackers for probing, prototyping, refining and sharing of security research

Adding the necessary hardware while refusing to support arbitrarily iLLegAl things is the best of both worlds.

The success of Flipper Zero was mainly of design, the lineaments of the product being previously understood

This is not a rational purchase - most of the rule breaking done with the zero is for fun or convenience

I've pretty much just used it as a toy to play snake on and a universal remote.
Mixed · May 2026 · in “Flipper One – we need your help”
I like the format of the Flipper and it has very few distractions except Snake
Recommends · May 2026 · in “Flipper One – we need your help”
you don't have full control over the device, which could be a limiting factor

The evolution that I could like is a Zero with more CPU power, SDR and LoRa.

They did their job very well, financed ONLY by one-time sales of hardware.
